Izinguquko ze-Epidermal ne-Biochemical ekugugeni kwesikhumba

I-metabolism ye-epidermis ukuthi ama-basal keratinocyte aqhubekela phambili ngokuhlukahluka kuseli, futhi ekugcineni afe ukwakha i-stratum corneum engekho emthethweni, bese ewa. Ngokuvamile kuzwakala ukuthi ngokwanda kweminyaka, ungqimba lwesisekelo kanye nongqimba we-spinous kuphazamisekile, ukuhlangana kwe-epidermis kanye ne-dermis kuba isicaba, futhi ubukhulu be-epidermis buyancipha. Njengesithiyo sangaphandle somzimba womuntu, i-epidermis ixhumana ngqo nemvelo yangaphandle futhi ithintwe kalula yizici zangaphandle zangaphandle. Ukuguga kwe-Epidermal kukhombisa kalula ithonya leminyaka nangezici zangaphandle ekugugeni kwabantu.

Ku-epidermis yesikhumba sokuguga, ukuhlukahluka kobukhulu, i-morphology kanye nezindawo zokubala zama-epidermis cell kuyanda, ukuhlangana kwe-epidermis kanye ne-dermis kancane kancane, futhi ubukhulu be-epidermis buyancipha. Ubukhulu be-epidermal buncipha cishe ngo-6.4% ngeminyaka eyishumi ngayinye, bese wehla ngokushesha ngisho nabesifazane. Ubukhulu be-epidermal buncipha ngeminyaka. Lolu shintsho lukhulunywa kakhulu ezindaweni eziveziwe, kufaka phakathi izindawo ezandisiwe zobuso, intamo, izandla kanye nezingalo. I-Keratinocytes Shintsha ukwakheka njengeminyaka yesikhumba, iba mfushane futhi inamafutha, ngenkathi ama-keratinocyte eba mkhulu ngenxa yokungena emfushane kwe-epidermal, isikhathi sokuvuselela amaseli e-epidermal ancipha, futhi i-epidermis iba mncane. mncane, okwenza isikhumba silahlekelwe ukuqina kanye nokugqwayiza.

Ngenxa yalezi zinguquko ze-morphological, i-epidermis-dermis junction ayiqinile futhi isengozini yokulimala kwamandla angaphandle. Inani le-melanocyte kancane liyancipha ngemuva kweminyaka yobudala engama-30, umthamo owandayo, futhi umsebenzi we-enzymatic we-melanocytes wehla ngesilinganiso esingu-8% -20% ngeminyaka eyishumi. Yize isikhumba singelula ukwenza ama-tan, ama-melanocytes athambekele ekwakhekeni kwasendaweni ukwakha izindawo ze-pigmentation, ikakhulukazi ezindaweni ezivezwa yilanga. Amaseli aseLangerhans nawo ancishisiwe, okwenza umsebenzi wokuzivikela emzimbeni wehla futhi wathambekela ezifweni ezithathelwanayo.

Isikhumba AnlayzerUmshini ungasetshenziselwa ukuthola imibimbi yesikhumba yobuso, ukuthungwa, ukulahleka kwe-collagen, kanye nobuso be-contour ukusiza ukuthola ukuguga kobuso.
